Online Writing Lab (OWL)
An Online Writing Lab is usually an extension of a college or university Writing Center. They offer help to students who submit papers electronically for feedback. Some writing centers are also open to people unaffiliated with the institution.
Purdue University Online Writing Lab
The Purdue University Writing Lab was founded in 1976 by Dr. Muriel Harris as a resource for Purdue writers. In an attempt to bring the Writing Lab to students no matter where they were, Dr. Harris and David Taylor started the world's first Online Writing Lab (OWL) in 1994.
